Keep ARM TWD and Global timer's nodes disabled by default - if someone would like to use them then those nodes have to be enabled explicitly in board file.
The reason for this change is: - ARM TWD is not always-on timer on am437x and it will stop in low CPUIdle states and, therefore, broadcast timer has to configured properly if CPU_IDLE=y. - ARM Global timer is not always-on timer on am437x and it can't be used as clocksource device if CPU_IDLE=y. - ARM Global timer driver doesn't support CPUfreq now.
